test1.mpg; if test1.mpg, test2.mpg and test3.mpg exist, and the Recorder File Name is still set at test.mpg, the new recording will start at test4.mpg. If the Recorder File Name is set at to particular index number, such as test2.mpg, the first file to be recorded will be test2.mpg and the batch recording will increment from that number.
Note The maximum batch file size is 4 GB. If an attempt is made to record files using the maximum file size (4 GB) in the maximum number of batch files (9), the files can exceed the hard disk drive storage capacity. If the files are large, it might be best to set a Batch Wrap Point.
Batch Wrap Point and Record Duration
A Batch Wrap Point sets the number of files to be recorded. When the specified number of files has been created, the previously recorded batch files will be deleted and recorded over, starting from the earliest file. For example, if a Batch Wrap Point is set to 10, and test.mpg is the Recorder File Name, the files will be recorded from test1.mpg, test2.mpg, up to test10.mpg.
Batch File Recording can be set to a specific number of seconds or Continuous. If Batch is enabled and set to Continuous, when the maximum number of batch files is reached, recording will record over the files previously recorded, starting from the first file. As one file is being recorded, the next index file is deleted to get ready to receive data (from 1 to 999). For example, if the wrap point is set to 10 and a batch file name is specified as test5.mpg, the files will be recorded (or recorded over) starting at test5.mpg and increment until test10.mpg is reached. When the number of files reaches the Batch Wrap Point of 10, the files will be recorded over starting with test1.mpg.
Note If VBStar encounters an interruption in file transfer during batch recording, the file being recorded and the next file will both be affected. The file in the process of being replaced will be partially recorded. The next sequential file that was deleted to get ready for receiving data will be missing.
